WRENCH.

SPECIFICATION forming part of Letters Patent No. 527,156, dated October9, 189% Application filed February 21,1894. Serial No. 501,007. (Nomodel.)

To all whom it may concern:

Be it known that I, WILLIAME. PUGSLEY,

acitizen of the United States, and a resident of Lincoln, in the countyof Lancaster, and in the State of Nebraska, have invented certain newand useful Improvements in Wrenches,

and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention has for its object to provide a simple, strong andeconomical wrench capable of ready adjustment to fit nutsand otherdevices of various diameter.

To this end the said invention consists in certain peculiarities ofconstruction and combination of parts hereinafter described withreference to the accompanying drawings and subsequently claimed.

In the drawings: Figure 1 represents a side elevation of my improvedwrench partly broken away; Fig. 2, a section of the same taken on line22 of the preceding figure, and Fig. 3 a perspective view of the lowerwrench- Referring by letter to the drawings, A represents a straighthandle-bar of suitable metal,

having its forward end curved upon the under side and offset to form anabrupt shoulder 17, this ofiset portion of the handle bar constitutingthe lowerjaw B of myimproved wrench.

Intermediate of its extremities the handlebar A is provided with aconcave socket for the half-round terminal 0 of the shank portion 01 ofan upper jaw O that is offset to form an abrupt shoulder e, curved uponits upper side and transversely serrated upon itslower side. A pivot fconnects the half-round end of the upper jaw-shank with a clip D boltedor otherwise rigidly secured'to the handle-bar. Loose on the handle-barand upper j aw-shank is a collar E and fast in this collar between saidbar and shank is a wedge-block F, the inclined face of the latter beinguppermost.

By a movement of the collar the spread of the jaws B, O, is regulated,and'the forward move-. ment of said collar is limited by the shouldersb, e, of said shoulder.

The opposing faces of the upper j aw-shank and the collarE may beprovided with engaging serrations whereby they willautomatically locktogether and prevent rear movement of said collar and wedge-block whenthe wrench screw G to positively lock the aforesaid collar andwedge-block in adjusted position. I also "prefer to provide the lowerjaw B with longitudinal flutes, as shown in Fig. 3, in order to improvethe grip of the wrench.

From the foregoing description it will be seen that I provide a verysimple wrench having its greatest strength where it comes upon a nut,pipe or other device to be turned the spread of the jaws to accommodatesaid wrench to devices of varying diameter being easily efiected by amovement of the collar having the wedge-block fast therein.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A wrench comprising a handle-bar having one end in the form of a jaw,another jaw having a shank pivotally connected to the handle-bar, acollar loose on the handle-bar and jaw-shank, and a wedge-block fast inthe collar between said handle-bar and jawshank, substantially as setforth.

2. A wrenchcomprising a handle-bar having one end in the form of a jawand provided intermediate of its extremities with a concave socket,another jaw provided with a shank having a half-round terminal engagingthe handle-bar socket, a clip fast on said handle-bar, a pivotconnecting saidjaw-shank terminal with the clip, and a sliding devicethat regulates the spread of the jaws, substantially as set forth.

3. A wrench comprising a handle-bar having one end in the form of a jaw,anotherjaw having a shank pivotally connected to the handle-bar, acollar loose on the handle-bar and jaw-shank, a wedge-block fast in thecollar between said handle-bar and jaw-shank,

and a set-screw for locking the collar in adj usted position,substantially as set forth.

4. A wrench comprising a handle-bar having one end in the form of a jawanother jaw having a serrated shank 'pivotallyconnected tothehandle-bar, a serrated collar loose on the handle-bar and jaw-shank, anda wedgeblock fast in the collar between said handlebar and jaw-shank,substantially as set forth.

5. A wrench comprising a handle-barhaving one end in the form of a jawprovided bar and jaw-shank, and a wedge-block fast in the collar betweensaid handle-bar and jawshank, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atLincoln, in the county of Lancaster and State of Nebraska, in thepresence of two Witnesses.
